It's not any more dead than it was when Pearl was pining for Rose Quartz the entire rest of the series. Ships don't die until somebody dies, and even then you can still ship it. Just because it isn't canon/contradicts canon, doesn't mean that it's dead.
So Pyrrha is derived from pyrrhic...which means that her death was planned all along, and she realised it so she hung herself by fighting Cinder. Thanks Rooster Teeth, for preemptively murdering our favorite character (and simultaneously sinking the best ship in the show). #RWBY #PyrrhaNikos #Pyrrha #WHY <<< of course I mean she is inspired by Achilles!
